searching parameter names

Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

hi,

Just wondering how i can search paremeter names? so if i had a form with input values with the names of "hello1", "hello2", "hello345". now the numbers after the word "hello" may be different depending on the end user, so i need a way to retreive all input values with the paremeter name having "hello" inside of it. does that require some sort of regex?

btw, I am using CGI.pm to parse form values.

Thanks,
bobby

You just need to search through all the parameter names looking for the ones which match you condition. If you're using CGI, you can do something like this. `my $q = new CGI; my @hello_param_names = grep {m/hello/} $q->param();` [download] --- my name's not Keith, and I'm not reasonable.	[reply] [d/l]

Thank you, works great. So to actually retreive the values, I would have to do a little foreach statement and then print the values. Is there a shorter way I can take this concept but instead of storing the names of the paremeters, just store the actual values of all paremeters with the world "hello". That way, I would have one less foreach statement in my code. I'll continue trying to figure it out and if I do, I'll repost it here for future ref.	[reply]

You mean like this? `my @hello_values = map { $q->param($_) } grep {m/hello/} $q->param(); # untested!` [download] --- my name's not Keith, and I'm not reasonable.	[reply] [d/l]

Hi try this, `#!/usr/local/bin/perl use CGI; my $q = new CGI; my $search_word = $q->param('search_word'); my @parameters = qw(hello1 hello2 hello345 gube); @values = grep /^$search_word\d+/, @parameters; print "@values";` [download] Always, mention the input clearly and ask the clear output in what output you need. And paste, the code what you have tried before and where you are struggle...	[reply] [d/l]
